The process of checking to see if a XML document conforms to a schema is called validation, which is separate from XML's core concept of syntactic well-formedness.All XML documents must be well-formed, but it is not required that a document be valid unless the XML parser is "validating", in which case the document is also checked for conformance with its associated schema.
RELAX NG has a simpler definition and validation framework than XML Schema, making it easier to use and implement. It also has the ability to use datatype framework plug-ins; a RELAX NG schema author, for example, can require values in an XML document to conform to definitions in XML Schema Datatypes.
They also include validation, bean creation, and commit tools. A plugin for Notepad++ named XML Tools is available. [4] It contains many features including manual/automatic validation using both DTDs and XSDs, XPath evaluation, auto-completion, pretty print, and text conversion in addition to being able to work on multiple files at once.
